Hundreds of Bahraini youths shouting anti-government slogans have taken to the streets in Bahrain despite a heavy police presence to mark the fifth anniversary of an uprising calling for political change in the tiny island kingdom. Graffiti on the wall reads "Al-Nimr Strike," the name the opposition chose for this year's anniversary protests, in honor of Shiite Sheikh Nimr al-Nimr, seen in stencil, who was executed last month in Saudi Arabia, and who had been a supporter of anti-government activists in Saudi Arabia and Bahrain.

FILE - In this Monday, Jan. 4, 2016, file photo, a Bahraini protester holds up a picture of Saudi Shiite cleric Sheikh Nimr al-Nimr, who was executed by Saudi Arabia, in Daih, the largely Shiite suburb of the capital, Bahrain. Within hours of ascending to the Saudi throne, King Salman announced sweeping changes that would recast the kingdom’s line of succession, and rework its security and economic decision-making processes. It marked the start of what would be a tumultuous year for King Salman, who completes one year as monarch on Saturday, Jan. 23, 2016. (AP Photo/Hasan Jamali, File)
